AERODYNAMIC TAB [6 records]

Record 1 2014-11-13

English

Subject field(s)
  • Aircraft Airframe
  • Aircraft Maneuvers
DEF

An auxiliary tab mounted on a flight control surface trailing edge to generate aerodynamic force.

CONT

Trim tabs are usually controlled from the cockpit by the pilot and are generally actuated manually or electrically.

CONT

Trim tabs [may be] adjusted on the ground before taking off. Trim tabs are installed on elevators, rudders, and ailerons.

Record 2 2014-10-21

English

Subject field(s)
  • Aircraft Airframe
  • Aircraft Maneuvers
CONT

A balance tab is similar in function to the control tab in that it is designed to assist the pilot in moving the control surface.... As the control surface begins to move in a certain direction, the balance tab moves in the opposite direction. This produces an aerodynamic force to help move the control surface. In some designs, the balance tab is combined in function so that it can be actuated in flight. In these cases it also serves as a controllable trim tab.

OBS

geared tab: term standardized by ISO.

Record 3 2010-04-15

English

Subject field(s)
  • Air Forces
  • Aircraft Airframe
  • Aircraft Maneuvers
CONT

Tabs are small secondary flight control surfaces set into the trailing edges of the primary surfaces. They are used for trimming the aircraft for straight and level flight at cruising speeds or for providing an assist for the pilot in moving the control surfaces. In the first case they are called trim tabs and in the second case, control or servo tabs.

OBS

Il peut être fixe, commandé ou automatique.

OBS

compensation: Correction de l'effet des réactions aérodynamiques sur les gouvernes d'un avion en vue de réduire les efforts sur les commandes de vol généralement obtenue à l'aide de surfaces auxiliaires appelées compensateurs.

Record 4 2010-04-15

English

Subject field(s)
  • Aircraft Airframe
  • Aircraft Maneuvers
CONT

Control and servo tabs are employed on large aircraft to assist the pilot in moving the primary control surface. When the pilot applies manual force to a surface control in the cockpit, the control or servo tab moves in a direction opposite the desired motion of the control surface. Aerodynamic forces against the tab produce movement of the control surface in the proper direction.

OBS

Servo tabs are very similar in operation and appearance to the trim tabs ... Servo tabs, sometimes referred to as flight tabs, are used primarily on the large main control surfaces. They aid in moving the control surface and holding it in the desired position. Only the servo tab moves in response to the movement of the cockpit control.

OBS

servo-tab: term standardized by ISO.

Subject field(s)
